lightsoder shades, that´s turning around a centerOn the way home (no beer or alcohol) there was a group of lights thats moves toward west. This ligths are rotating in group around a center in one direction for nearly 180 degrees than stop for a half second an turn back. This repeats while the groupt slow moves toward north. The formation has a round corner. There was at least 9 ligths in the group. They have a low intentsity and a nearly round form with some structures. The turning cycle was very exact. This means they turn, stop and turn in other direction very exact. The sky was cloudy an for my meaning they where above the clouds. I have never seen such lights before, i´m not a UFO-Believer and was in military service (close air defense) in from 1989-1990. There are no craft i know, that´s looks similiar. Please excuse this bad english because i not often use it.
